This study was conducted to theoretically analyze the overturning axes of curved box-girder bridges with three equal spans and single-column piers per the influence of curvature radius and bearing eccentricity on overturning axis. The theoretical analysis is verified by a model bridge experiment. The results show that overturning axis can be effectively determined according to the connecting line of either bearings at the central piers or outmost bearings at abutments as influenced by curvature radius and bearing eccentricity. In other words, no bearings are outside of overturning axis. All the bearings but the two on the overturning axis are located on the inner side of the axis. For curved bridges with multispans and single-column or double-column piers, the overturning axis is characterized by the connecting line of the two adjacent outmost bearings.

<p>The Darlington Upgrade Project (DUP) consists of the upgrade of approximately 3.3 kilometres of the existing Main South Road forming part of the Adelaide North-South Transport Corridor.</p><p>This paper focusses on the design of the project’s three composite steel box girder bridges and challenges employing the Design for Manufacture and Assembly (DfMA) principles on the bridge superstructures which were constructed on temporary towers in an assembly yard approximately 500 metres from the final bridge position and transported using the Self-Propelled Modular Transporter (SPMT) technology. SPMTs, a first in Australia for bridge application, allows pre- fabrication of the bridge superstructure improving safety for both construction crews and motorists.</p><p>Evaluation of stresses imposed on the superstructure obtained from the real time monitoring instrumentation during installation is also presented.</p>
